So I want to use XBOX 360 controller on PC, I have searched throughout internet, yes there are a lot of explanation about it. The explanation about it is really hard for me understand (since my english is not that good)
All I understand are : need XBOX 360 controller, program or software to identify the XBOX 360 controller, and some wireless reciever for wireless XBOX 360 controller.
Since some games that I play required XBOX 360 controller and the game didn't identify my dualpad controller right, so it's a bit mixed up in game. Like camera control, camera up is identify to camera right, 3 (which is A in xbox360) is identify to 1 (which is Y in xbox360)

So will it really work? If it work I'll buy it. Because if I buy XBOX 360 controller and in the end it didn't work, it will waste my parent's money. If anyone know or already use XBOX 360 controller on PC and know how to set it up, please help.

And a question about STEAM, I have found STEAM card, Thanks to escobert for the information, and now I have some money in STEAM wallet. After I put the game in my cart will STEAM ask for another confusing stuff or just pay and download?

Thanks
